CAR OR ENGIYHNEI REPLACER.

SPECIFICATION forming part of Letters Patent No. 706,542, dated August 12, 1902.

Application filed December 5,- 190].- erial No. 84,802. (No model.) i

To all. 1.0720122, it may concern.-

Be it known that I, FREDERICK J. FEWINGs, acitizen of the United States, residing at Duluth, in the county of St. Louis and Stateof Minnesota, have invented new and useful Improvements in Car or Engine Replacers, of which the following is a specification.

This invention .relates to certain new and useful improvements in car and enginereplacers. The invention aims to construct a car and engine replacer consisting'of an outer and an inner replacing-block which are so constructed as to prevent the car or engine wheels from slipping backwardly'and, furthermoregless liable to turn over or jump out of place when struck by the car or engine wheels, and which will also lower the wheels gradually toward and upon the rails without allowing the wheels to slide down in a lateral direction and land with a sudden jar upon the rails.

The invention further aims to construct a pair of replacing-blocks which shall be extremely simple in their construction, strong,

durable, efficient in their operation, and comparativelyinexpensive to manufacture; and to this end the invention consists in constructing the replacingblocks with their upper face upon a compound curve extending from one end of the blocks upwardly'to the'center and then downwardly toward the opposite end of the blocks, forming thereby at the center of the blocks a ridge of convex curvature transversely as well as longitudinally, said ridge being slightly higher at one edge than at its opposite edge and curving downwardly from the said higheredge to the saidlower edge; further, providing upon the upper face of the outer replacing block a pair T of diagonally-extending ribs of concave curvature longitudinally and which terminate at their upper ends in-said ridge of the outer replacing-block, and,- further, providing the inner replacing-block at its inner edge with a rib extending from endto end thereof and of concavo-convex curvature.

The invention further resides in providing the replacer-blocks with suitable strengthening and fastening means to be hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

Fig. 2 is a plan view thereof. Fig. 3 is a side elevation of one of-the blocks. Fig. Fig. 5

verse section, of onebf' the blocks.

Referring to the drawings by referencenumerals,.1 denotes the outer replacingblock, and 2the inner'replacing-block. The

former is adapted to be arranged at the outside of and abut against the rail 3 and is of such height at both sides thereof to suitably extend above the said rail 3, and the latter is adapted to be arranged at the inside of and abut against the rail 4 and is of such height as to suitably extend at one side above the rail and at its opposite side below the tread The function of constructing will be hereinafter described in the operation of replacing acar or engine.

Each of the blocks l 2 is constructed, preferably, of cast-steel and of; shell formation, with an'open'bottom, and each is provided interiorly with a pair of centrally-arranged transverselyextending vertical web-braces 5 and a pair of Web-braces6 7 at each side of the web-braces 5, the braces 6 7 extending at an angle to the vertical brace 5 and arranged a suitable distance apart. Constructing and arranging the web-braces in the manner set forth will strengthen the blocks to such an extent that it would almost make the breaking thereof impossible.

One side of the blocks 1 2 extends in avertical manner, as at 8, andthe opposite'side extends upwardly and inwardly at an inclination, as at 9. The reference-numeral l0 denotes an outwardly-extending flange integral with the bottom of the side 9 of each of the blocks and has formed therein a series of openings 11, registering'with a series of recesses formed by the depressed portions 12, arranged in the sides 9 of each of the blocks. The recesses and openings are adapted to receive spikes or other suitablefastening means,

securin g the blocks thereto when in operative position.

The sides 8 of each of the blocks 1 2-that is, the side which abuts against the rails-is provided centrally, near the top thereof, with a countersunk opening 13, in which is mounted the head of a hooked bolt 14, the latter extending into its respective block. The inner end of each of the. hook-bolts 13 is connected to an eyebolt 15 in the form of an L- shaped connecting-arm, the vertical member of which is arranged within the respective block therefor and the horizontal member of which extends below the base of the rail and is connected thereto by means of the sleeve 16, carried by the said horizontal member of the connecting-arm. The sleeve 16 is provided with a clamping-offset 17, which engages the base of the rail and is held in engagement therewith by means of a bindingnut'18, mounted on the screw-threaded end 19 of the horizontal member of the connecting-arm. The eyebolt or connecting-arm 15 and clamping-sleeve 16 retain the blocks rigidly in position against the rail, at the top thereof, which is the point of greatest strain whenthe blocks are used for replacing a car from one end of the block upwardly to the center and then downwardly toward the opposite end of the block, forming thereby at the center of the block a ridge 21 of convex curvature transversely as well as longitudinally, this ridge extending from side to side of the block and so constructed as to curve downwardly from one edge of the block to the other. This downward curvature is caused by the sides 8 of the block being lower than the sides 9. Constructing the upper face of the blocks in the manner set forth, when' either the car orengine mounts onto the reverse curve, which forms a pocket in the upper face of the block, near each end thereof, it will tend to hold the block in position much better than the ordinary inclined curve generally employed. Furthermore, the reverse curve, or rather pocket formed by the reverse curve, will materially assist to prevent the car or engine from slipping backward when riding upon the blocks.

' The upper face of the outer block 1 is provided with a pairof ribs 22 of concave curvature longitudinally and each of which extends diagonally from the outer corner at each end of the block 1 toward the ridge 21 and terminates at its upper end in the said ridge at a point adjacent to a transverse and longitudinal line of the center thereof. The upper face of the inner replacing-block 2 at its inner edge is provided throughout its length with-a rib 23, of convexo-concave curvature longitudinally. This rib 23 extends from one corner of one end of the block 2 diagonally upward toward the center of the inner edge and then downwardly to the corner at the opposite end of the block 2, or, in other words, the rib 23 extends substantially in the same manner as the pair of ribs 22. The pair of ribs22 are adapted to aid the rib 23 on the inside replacer and divide the strain on the wheel-flanges between the two wheels instead of leaving all the strain on the rib 23, as would be the case without the employment of the pair of ribs 22, and this construction is especially adapted for the heavy class of equipment now coming into general use. Furthermore, constructing and arranging the pair of ribs 22 in the manner set forth will preventthe wheels from ever mounting them, as thecurve will gradually force the wheel to one side, and at the same time the weight will be distributed by the ball of the wheel resting on the ribs.

From the foregoing description it will be apparent that when the blocks are placed against the rails and the wheels are advanced upon them as soon as the wheels approach the ridge of the blocks the inwardly and downwardly extending curvature thereof will cause the Wheels to slide over and upon the rails, the ribs 22 and 23 materially assisting in cansing the wheels as they mount the blocks to move toward the rails.

It is thought the many advantages of my improved replacing-block can be readily understood from the foregoing description,taken in connection with the accompanying drawings, and it will also be noted that minor changes may be made in the details of construction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.
